Hydrogeological Characteristics of a Karst Mountainous Catchment in the Northwest of Vietnam

Acta Geologica Sinica(English Edition) 2001年第3期75卷 260-268页

This paper presents a preliminary assessment of the hydrogeological characteristics of a karst mountainous catchment, the Suoi Muoi River catchment, in the northwest of Vietnam. The catchment is located at 600–700 m a.s.l. and covers an area of 284 km. Exposed limestone occupies 32% of the total catchment area. Various types of assessments have been carried out, including geological and hydrogeological field surveys, cave surveys, dye-tracer tests, meteorological and surface water monitoring. Geological studies and cave surveys have identified the most important active cave/conduit systems within the catchment. Although these data are essential, they are insufficient to make a comprehensive appraisal of the hydrologic nature of the catchment under interest. An attempt was made to calculate a global water balance of the catchment, based on short-term (15 months) meteorological and streamflow records. The results show that, despite the existence of a number of substantial cavern conduit systems, the groundwater system of the catchment is governed by the fracture/fissure matrix. The cavern conduit systems only collect groundwater from the adjacent fracture matrix and/or connect topographically isolated surface watercourses. The groundwater storage of the cavern conduit systems appears to be regionally insignificant in comparison with the governed fracture matrix groundwater system.

全球气候变化导致盐湖数量急剧减少，对未来盐湖资源供应带来了严峻的挑战。本文通过大量的文献资料，归纳了澳大利亚盐湖的主要分布特征、盐湖资源潜力区，收集了澳大利亚典型盐湖两个时期（1970s～1980s和2000s～至今）的水化学数据和近40年（1986～2023年）盐湖面积变化数据，分析了澳大利亚盐湖的资源环境变化，并提出了三点展望。本文对澳大利亚盐湖资源保护以及海外投资开采盐湖资源方面具有一定的指导意义。
